I am unable to mount ntfs partitions on my hd.I found this wiki article and followed it: http://wiki.centos.org/TipsAndTricks/NTFSPartitions) but in the end its not working. I am giving the output of the things i think are important. Please tell me what the problem is. I will post any more outputs that are required if you can tell me the commands to run.

Machine has centos5.1 installed, pentium 4 processor.

$ mount -t ntfs /dev/hda1 /mnt/video
mount: unknown filesystem type 'ntfs'
$ mount -t ntfs-3g /dev/hda6 /mnt/video
FATAL: Module fuse not found.
fuse: device not found, try 'modprobe fuse' first

$ rpm -qa | grep rpmforge
rpmforge-release-0.3.6-1.el5.rf
$ rpm - qa | grep fuse
fuse-ntfs-3g-1.1120-1.el5.rf
fuse-2.7.0-2.el5.rf
dkms-fuse-2.7.0-1.nodist.rf

$ uname -r
2.6.18-53.el5
$ rpm - qa | grep kernel-devel
kernel-devel-2.6.18-53.1.4.el5

All i can see is that kernel and kernel-devel versions are different (as in http://bugs.centos.org/view.php?id=2376)
I have not done any changes to the kernel, infact all i have done on the machine is something like "yum install fuse fuse-ntfs-3g dkms dkms-fuse"

Thanks

Did you try this?
Is fuse listed in your lsmod output?

It turns out the incompatibility of the kernel with the devel package was the issue.
I think that when I installed the packages with "yum install fuse fuse-ntfs-3g dkms dkms-fuse" the devel pkg was automatically upgraded to the next version while the kernel was left as it is.
So the solution was updating the kernel.
yum list available kernel\*
yum install kernel-2.6.18-53.1.4.el5

So any other newbies facing NTFS mount problems on centOS
First follow the steps on this page: http://wiki.centos.org/TipsAndTricks/NTFSPartitions
Then check versions of your kernel and devel package with
$ uname -r and $ rpm - qa | grep kernel-devel
If they differ upgrade as required.
Upgrading the kernel is a one line command listed above.
Then you can choose to boot with the new kernel at boot time, grub shows two options of linux - named with the kernel version.

Anyways, thanks for answering JivanAmara

If you use fuse, also install the ntfs-3g package if it isn't installed. Instead of using the "ntfs" filesystem, use the "ntfs-3g" filesystem.

It is also possible that you had ntfs supported by the kernel but you just needed to modprobe the "ntfs" kernel module. Also, you need to run your mount command as root, so precede the command with "sudo":
sudo mount -t ntfs-3g /dev/hda6 /mnt/video
or
sudo mount -t ntfs /dev/hda6 /mnt/video

Also, read the mount manpage. You want to either use "uid=" so that you are the owner of the partition, or use the fmask & dmask options to give you permissions as the "other" user.

for example:
sudo mount -t ntfs-3g /dev/hda6 /mnt/video -o rw,uid=<yourusername>,fmask=117,dmask=007
or
sudo mount -t ntfs /dev/hda6 /mnt/video -o rw,fmask=111,dmask=000
